The invention discloses a pickup device and a microphone array structure. The pickup equipment comprises at least three groups of linear microphone arrays arranged along different axial directions, each group of linear microphone array comprises at least two microphones, the axial directions are used for representing the arrangement direction formed by the positions of the microphones in the linear microphone arrays, and the at least three groups of linear microphone arrays are used for forming a plurality of wave beams. Each beam indicates a pickup area, and the plurality of beams include a first beam formed based on a set of linear microphone arrays and a second beam formed based on two sets of linear microphone arrays. Therefore, the superposition of the pickup areas indicated by various beams provided by the pickup equipment can meet the pickup requirement of a large-range scene area. Moreover, the pickup equipment is compact in overall structure, and can be fixedly installed at a position (such as the top of a building) in practical application, and there is no need to arrange one pickup equipment at each of a plurality of different positions.
Description
technical field [0001] The present disclosure relates to the field of signal processing, in particular to a sound pickup device and a microphone array structure. Background technique [0002] How to pick up sound in a large-scale scene area is a technical problem that needs to be solved urgently. [0003] In the industry, it is mainly through arranging multiple microphones in different positions to pick up sound in a wide range of scene areas. This solution makes the structure of the sound pickup device not compact, and it is cumbersome to arrange. [0004] Therefore, for a large-scale sound pickup scene, it is necessary to design a sound pickup device with a more compact structure. Contents of the invention [0005] A technical problem to be solved in the present disclosure is to provide a sound pickup device with a more compact structure for a wide-range sound pickup scene. [0006] According to a first aspect of the present disclosure, a sound pickup device is provid...
